Water is the enemy of every chimney in Towson. The freeze-thaw cycles we get through winter here, especially in older neighborhoods like Rodgers Forge and Stoneleigh, will destroy an unprotected chimney crown in just a few seasons. We’ve seen it hundreds of times: a homeowner notices a water stain on the ceiling near the fireplace, and the root cause is a cracked crown that should have been sealed years ago. Or the cap blew off in a storm, and now squirrels are nesting in the flue. These are not dramatic failures. They’re slow, expensive problems that could have been prevented with the right cap or crown work done correctly the first time.

We’re Hearthstone Chimney Co., founded in 1984 and led by Russell Haines. Our technicians are background-checked and uniformed, and we answer the phone with a live person 24 hours a day, 7 days a week. When you call (443) 785-3816, you’ll speak to someone who can book your appointment, not a recording promising a callback. We document every inspection with photos you can see and a plain-English verdict, and we give you no-hassle upfront pricing so the number on the estimate is the number on the invoice. That’s a square deal.

What Our Chimney Cap & Crown Service Includes

Cap Installation

A chimney cap is the metal cover that sits atop your flue, keeping rain, animals, and debris out while letting smoke escape. In Towson, where mature oak trees drop leaves and acorns straight into uncapped flues, and where raccoons are a persistent problem in neighborhoods like Wiltondale and West Towson, a proper cap is essential protection. We measure your flue precisely and install caps from Famco, Gelco, and Copperfield, secured with stainless steel fasteners that won’t rust out in our humid summers. Every installation includes a visual inspection of the crown beneath, because there’s no point in capping a chimney that’s already crumbling.

Cap Replacement

Caps don’t last forever. Galvanized steel caps rust through in 5-7 years in Towson’s climate, and even stainless caps can fail at the seams or get damaged by falling branches. We remove the old cap, inspect the flue tile for cracks or spalling, and install a replacement that fits correctly. A cap that’s too large catches wind and blows off; one that’s too small doesn’t protect properly. We stock common sizes for immediate replacement and can order custom fits for unusual flue configurations. Most cap replacements in Towson are completed in under an hour.

Crown Repair

The crown is the concrete slab that covers the top of your chimney, sloped to shed water away from the flue. When it cracks, water seeps in, freezes, expands, and destroys the masonry from the inside out. In Towson’s older homes, especially in neighborhoods like Anneslie and Aigburth Vale, we’ve found crowns that were poured too thin or without proper reinforcement, failing prematurely. We also serve our Chimney Cap & Crown in Cockeysville customers with the same thorough approach. We repair minor crown damage with professional-grade crown sealant, properly prepared and applied so it bonds and flexes with temperature changes. For more significant damage, we cut out the compromised section and pour new concrete with the correct slope and overhang.

Crown Coating

Crown coating is a preventive treatment for crowns that are sound structurally but showing early hairline cracks or surface erosion. We use HeatShield, a professional-grade refractory coating formulated specifically for chimney crowns. The surface is cleaned, cracks are opened and filled, and the coating is applied to create a waterproof, flexible membrane that bridges small cracks as they develop. In Towson, where we average 42 inches of rain annually and temperature swings from single digits to near 100 degrees stress every crown, this treatment can add 10-15 years of service life to a sound crown. We only recommend coating when the crown is fundamentally sound; if it’s too far gone, we’ll tell you plainly and recommend repair or rebuild instead.

Multi-Flue Cap

Many Towson homes, particularly the larger colonials and Cape Cods in neighborhoods like Ruxton and Hampton, have multiple fireplaces sharing a single chimney structure. A multi-flue cap is a single cover that protects two or more flues at once, with better structural stability and a cleaner appearance than individual caps. We measure the full chimney top, fabricate or order a cap with the correct flue openings and mesh screening, and anchor it properly so it withstands wind uplift. Multi-flue caps also improve draft performance by creating a more stable pressure zone across all flues.

Custom Cap

Some chimneys need what no catalog carries. We’ve fabricated custom caps for historic homes in Towson with oversize or irregular flues, for chimneys with external pullies or antenna mounts that standard caps can’t accommodate, and for homeowners who want a specific finish to match their home’s architecture. We work with Copperfield for custom copper and stainless fabrications, and we can match powder-coat colors to your trim. A custom cap costs more and takes longer to produce, but when it’s the only solution that works, we make sure it’s done right and we stand behind it.

Brands We Service for Chimney Cap & Crown

We’ve installed and serviced hundreds of Famco caps across Towson and Baltimore County. Famco’s stainless steel line holds up particularly well in our climate, and we keep their most common sizes in stock for same-visit replacement. When we encounter a Famco cap that’s been damaged by weather or impact, we can typically match the exact model and mounting configuration, which matters for homeowners who want consistent appearance on multi-flue or multi-chimney homes.

Copperfield is our go-to for custom and decorative caps, especially in Towson’s historic districts where homeowners want the look of traditional copper that weathers to a green patina. We’ve worked with Copperfield fabricators on everything from simple custom sizes to elaborate designs with finials and custom mesh. Whether you have a Famco, Copperfield, DuraFlex, HeatShield, Gelco, Olympia Chimney, or any other make, we can help. We don’t limit our service to brands we sell; if it’s on your chimney, we’ll inspect it honestly, repair it if it makes sense, and replace it with the right product if it doesn’t.

Signs You Need Chimney Cap & Crown Right Now

• Water stains on the ceiling near your fireplace. This is the most common symptom we see in Towson homes, and it almost always traces back to crown failure or a missing cap. The water runs down the flue, soaks into the surrounding framing, and shows up as a brown stain on the drywall. By the time you see the stain, the damage behind the wall has been progressing for months or years.
• Pieces of concrete on the roof or ground near the chimney. Crown concrete spalls off in chunks when water freezes in cracks. If you’re finding gravel-like debris below your chimney, your crown is actively disintegrating. In Towson’s freeze-thaw climate, this accelerates rapidly once it starts.
• Rust stains on the chimney face or fireplace surround. Rust means water is getting in and reaching metal components: the damper, firebox, or possibly the liner. A proper cap and sound crown keep water out; rust stains are evidence they’re not doing their job.
• Animal sounds or odors from the fireplace. Squirrels, raccoons, and birds enter through uncapped flues or gaps around damaged caps. We’ve removed nests from Towson chimneys in every season, and it’s never convenient. A properly fitted cap with the right mesh size prevents entry without restricting draft.
• White efflorescence on the exterior brick. That chalky white deposit is minerals left behind when water evaporates out of the masonry. It means water is getting in somewhere, and the crown is the most likely culprit. Left unchecked, the freeze-thaw cycle will spall the brick faces and require repointing or rebuilding.

We photograph the crown, cap, flue interior, and any damage we find. You see the photos. We explain what we’re seeing in plain English, not contractor jargon. If the crown is sound enough for coating, we’ll say so. If it’s failing and needs rebuild, we’ll show you exactly why.
3. 3
   Upfront pricing with options. Before any work begins, you get a written estimate with clear options. Cap replacement is one price. Crown repair is another. Full crown rebuild is a third. The number on the estimate is the number on the invoice. No surprises, no pressure.
4. 4
   Professional installation with quality materials. We use the right product for your chimney: Famco or Gelco for standard caps, Copperfield for custom work, HeatShield for crown coating. Every cap is secured with stainless fasteners. Every crown repair is sloped correctly and sealed to shed water. We don’t use builder-grade substitutes.
5. 5
   Final documentation and 90-Day Done Right Promise. When the work is complete, we photograph the finished job and review it with you. You get our 90-Day Done Right Promise in writing: if it’s not right, we make it right, no paperwork, no arguing. That’s the Keystone Standard we’ve operated by since 1984.
